AXLE-BEARING.

SPECIFICATION formingpart of Letters Patent No. 233,068, dated October 12, 1880.

Application filed March 5, 1880.

To all whom it may concern Be it known that I, CHARLES E. (JANDEE, of St. Louis, Missouri, have invented a new and useful Anti-Friction Bearin g for Axles, Shafts, 860., of which the following is a specification.

My invention relates to improvements in axle-boxes for railway purposes, or to an improved bearing to support the journals ot'sh afts, 85.0., in general.

The objects of my improvements can be stated to be to form the box or housing containing the journal of the axle, &c., to have separate chambers, one of said chambers to contain the parts that form the anti-friction bearing, the other chamber containing the parts that automatically apply the lubricant material to the operating parts contained in both chambers, and all said parts combinedly operating to produce the advantages, as will hereinafter appear.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal sectional elevation. Fig. 2 is a cross-section taken on line w m,- Fig. 3, a cross-section taken on line a 00. Fig. 4 is an enlarged detail elevation of the lubricating-disk and its cup, Fig. 5 being a cross-section of Fig. 4.

Similar letters refer to similar parts throughout the several views.

A is the box or casing to contain the operating parts. The box Ais made closed on all sides, its bottom A being a basin to contain the lubricant, its top A being a cap, and said sides, bottom, and top are all properly jointed together to exclude dust and prevent leakage of the lubricant material. Further, I form the box A to consist of two chambers, 13 B, the former to contain the revolving parts, such as the anti-friction wheels and journal of the axle or shaft, the latter chamber to contain the revolving disk with cups for lubricating purposes. The box A is therefore divided by the partition b, as shown more clearly in Figs. 1 and 2. This partition has an opening, b, below, so that the lubricating material can be at the same level in the basin of both chambers B B, and to freely communicate from the one to the other. Also, at W, an opening is made, say, near top (or can be at the diametrical ends) (Model.)

of the partition. Through said opening or openings the cups of the disk-wheel discharge their contained lubricant into the opposite chamber, B, for purposes of keeping the antifriction bearing continuously lubricated.

The anti-friction bearin g consists of wheels 0 c 0 and each of these I arrange in the operative relationship to the journal of the car axle or shaft 0 within the chamber B, in manner followingrThe car-axle has its journal passing through a stuffing-box at D, the outer end of said journal turning freely in the partition I), as shown in Figs. 1, 2, 3. The two small wheels 0 0 turn 011 their respective centers or pintles,which have theirbearin gin the opposite sides of the box. 7

By referring to Fig. 2, the special arrangement of the wheels 0 c is shown to be on the opposite sides of the journal of the axle; but more specially be it noted that the center of each of said wheels, though being on a straight line, are yet slightly above the center of the journal of the axle. The coincidence of the outer circle of each wheel 0 o with the cylindrical face of the journal of the axle or shaft may thus always be assured. The said wheels 0 0, thus arranged, act to steady the action of the journal and prevent its lateral or oscillating play. The large or top wheel 0 also turns by its pintle in the sides of the box. The said wheel I arrange so that its circumference bears only upon the journal, as shown in Figs. 1, 2. The juxtaposition of all the wheels 0 c c is therefore such that each and all are acted upon by the revolving journal of the axle or shaft at the same time, the friction of said parts beingreduced to a minimum.

By referring to Figs. 1, 2, it will be seen that a rolling bearing exists between the large wheel 0 and the journal of the axle, the latter in its revolution solely revolving the former, as stated. Also, that a rolling bearing exists between each of the small wheels 0 c and the journal of the axle, the latter again imparting revolution to said wheels. No contact exists between the small wheels and the larger or top wheel, and hence, especially for railway purposes, I am enabled to relieve the said,

smaller anti-friction wheels from hearing the weight of the car, said weight being in this case solely borne by the top wheel and its latter can freely dip into, retain, and only disber in which the lubricant can so collect or be bearing upon the journal of the axle. These advantageous results not only reduce the draft of each car, but achieve a saving in wear and tear, and otherwise insure economic service.

My improvements to achieve a continual lubrication of the revolving parts contained in the box are as follows: The outer end of the journal has a pinion, e, fitted to mesh with the internal toothwheel 0 of a disk-wheel, E, as shown in Figs. 1 arid 3. The action of the journal is therefore to impart a slow motion to the disk-wheel E and its cups f, so that the charge the lubricant at the proper pointviz., through the opening b ofthe partition-to flow into the opposite chamber 13. (See Fig. 1.) It is the hollow of each cup that forms the chamdipped from the basin or bottom of the box. The circumferential body of the disk-wheel E itself can be made to have the lubricant-chant bers f, as shown; or separate cups, the hollow of which, as just stated, can constitute the chambers f, can be secured to the said diskwheel. In either case, I prefer that the inside of the cups or chambers f shall be beveled in the direction of the opening b in the partition, (see Fig. 1,) and when in line with same. The openings shown atf and f of the cups serve for outlet and vents.

The disk-wheel so provided with the cups f revolves on its pintle c and otherwise is fitted snugly between the partition I) and the 4 side of the box. It is therefore when each cup f reaches its lowest point that it fills with oil, and the same is retained until the cup reaches its highest point, which is directly in line with the opening I) in the partition; then the oil flows out of the cup into the chamber B, to lubricate its revolving parts. At every revolution of the disk-wheel E lubrication of the parts contained in the box is insured, and the latter cannot become hot even at the highest speed of the car.

What I claim is- 1. The box A, divided into chambers B B, the partition I), having openings at b 12 the. journal 0, having pinion e, the disk-Wheel E, having toothed wheel 0, and cups f, having openings f f, said parts being combined and operating as and for the purposes set forth.

2. The combination of the parts, viz: the box A, having partition I), with openings at b If, forming the chambers B B, the former containing the wheels 0 0 0 the journal 0, the latter chamber having a disk-wheel, E, meshing with said journal, and said wheel carrying cups f, havingj' openings at f f, forming the improved lubricated and anti-friction hearing, as set forth.

In testimony of said invention I have hereunto set my hand.
